Well, things didn’t really go as planned yesterday... fuel pressure would increase with boost only a few PSI, then fall off... not even under full load... my tuner thought it might be due to a plumbing issue that I may have missed. Since all I had was the mini fuel pressure gauge in my engine bay, I ordered an in-cabin gauge to install and confirm I fixed it before going back to the tuner. Pretty disappointing to drive 7 hours round trip, spend $300 and have nothing to show for it.
Gauge is coming next week, tuning appointment Oct 1st, anxious to find root cause of the issue!
